This can be simplified slightly to:

Prelude > putStrLn . unlines . map show $ [(x, y, x && y) | x <- [True, False], y <- [True, False]]

This can be further simplified to: putStrLn $ unlines [show (x, y, x && y) | x <- [True, False], y <- [True, False]] -- Met vriendelijke groet, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ -- Using Opera's revolutionary e-mail client: https://secure.bmtmicro.com/opera/buy-opera.html?AID=789433
